The Norman Friedman Illustrated Design History series of U.S. warships books has been an industry standard for three decades and has sold thousands of copies worldwide. To mark and celebrate this achievement, the Naval Institute Press is proud to make these books available once more. Digitally remastered for enhanced photo resolution and quality, corrected, and updated, this series will continue to serve—for scholars and enthusiasts alike—as the foundation for U.S. naval warship research and reference for years to come. U.S. Submarines Through 1945 is one the most comprehensive references available on the entire development of U.S. Submarines from the first commissioned undersea fighting vessel, Alligator, in 1862, to the S boats of World War I, and the feared fleet submarines of the Gato and Balao classes of World War II. Like the other books in Norman Friedman's design-history series, U.S. Submarines Through 1945 is based largely on formerly classified internal U.S. Navy records. Friedman, a leading authority on U.S. warships, explains the political and technical rationales of warship construction and recounts the evolution of each design. This volume is fully illustrated with deck plans, outboard profiles, sketches from major design studies, and numerous detailed photographs complement the text.
